VastPark developer zone

In my enthusiasm to explore, I installed and launched for the first time Publisher 0.98, and dutifully entered a VastPark user ID that I had created for myself -- before I had requested a Metaforik login.

I have an S3 bucket that I would like to use, but can not reach it with Publisher from this machine because I have not figured out how to ever revisit the user ID login screen that I saw on that first launch of Publisher.

On another machine, at work, I installed Publisher for the first time and ran the initial login using my Metaforik ID, and I was able to set Publisher to use my group's S3 space. No problem there, except that 3ds Max is not on that machine :^(

Here at home, I'd very much like to get Publisher connected at home in the same way, but these haven't worked:
- Uninstall / reinstall Publisher 0.98
- Uninstall & search for vast items in my Documents and Settings, reinstall
- Uninstall, remove vast items related to VastPark installs anywhere, similar for registry search, and reinstall
- send request and add the VastPark user name that I first used to a same-named member of my group on Metaforik

It would seem that all I need to be able to do is invoke Publisher 0.98 in some manner that passes me through that initial set-user-ID screen, and I believe that after that, my S3 credentials would work, as they do on my work machine.
